Abstract:	摘要： Quantum size ZnO crystals have been synthesized successfully by a room temperature sol-gel process using oleic acid (OA) as capping agent to control the particle size. The particle size and structure of ZnO nanocrystals have been charactirized by X-ray diffraction (XRD), transmission electron microscope (TEM) and Raman spectra analysis methods. The sensor based on ZnO powder calcined at 400 °C for 1 h exhibits the highest response of 280 to NO 2 and the selectivity to CO and CH 4 at the same concentration reaches 31 and 49 at operating temperature of 290 °C. The effect of calcination temperature on the performance of gas sensing has also been studied. 其他題名： JSEN 出版者： IEEE 出版日期： 2012-05 出處： IEEE sensors journal, 2012-05, Vol.12 (5), p.1122-1126 資源來源： IEEE Xplore (NTUSG) 識別號： ISSN: 1530-437X 識別號： EISSN: 1558-1748 識別號： DOI: 10.1109/JSEN.2011.2166152 識別號： CODEN: ISJEAZ
